Merge lp:~jcsackett/launchpad/blueprint-private-traversal-deptree into lp:launchpad

[j.c.sackett]

Adjusts Specification:+deptree to filter for private specs.

Summary
=======
Much as with the SVG graph in Specification:+index, Specification:+deptree
is not privacy aware and 403s when a person who can't see a dependency or
blocked specification tries to access it. It should, as with the graph, merely
remove the specs the user doesn't have permission for.

Preimp
======
None--extension of previous work.

Implementation
==============
The deptree view has been updated to use the filtered all_deps and all_blocked
methods created in the branch this branch depends on. It has also had new
methods added, "dependencies" and "blocked_specs" that filter the attributes
of the same name from the context. As these are all used multiple times in the
template, they are cachedproperties.

The blocked_specs and dependency portlets used on this page are also adapted
to accept the view rather than the context, so that they can use the new view
methods.

Tests
=====
bin/test -vvct TestDepTree

QA
==
Ensure Specification:+deptree loads appropriately in situations of mixed
blueprint visibilities.

LoC
===
Part of private projects.

[Richard Harding (rharding)]

Looks ok to me. As someone not familiar, is there something that tests that if you try to pull up where the root itself is non-public?

review: Approve

If you're trying to pull up the root the usual 404 for a spec you can't see occurs, based on our standard privacy rules. See bug #1076477 and the linked branch.
